Just as noise pollution negatively impacts human health, it also affects wildlife. It can affect animal communication, their abilities to find food and impact where they live. A recent study published in Biology Letters found that human-created noise is affecting a wide range of animals. Noise pollution is caused by cars, trucks, airplanes, ships, factories, industrial activities and sounds from cities, among others. Researchers found that wildlife in many different land and water ecosystems showed significant responses to human-created noise.

For example, bats use ultrasonic sound waves to get around and to find food. However, noise pollution affects this and causes them to spend more time and energy locating their food source. Shipping lanes in the UK can be deafening to harbor seals, and noises from ships are seriously impacting killer whales ability to find food and avoid potential dangers, according to episode 2 of CBC s Killers: J pod on the brink (边缘). And it’s no secret that many human-created conditions, like noise, are changing the behavior of birds. You may be surprised to learn that plants are also impacted, since pollinators (传粉昆虫) often relocate to quieter areas.

Not unlike the impact of light pollution on insects, noise pollution is causing change. It can change the types of species living in many different ecosystems, which in turn impacts the functions of these areas, according to The Guardian.

The good news is that if noise is reduced or simply turned off, it more or less removes the issue. The impact does not remain in the same way as other forms of pollution, like plastic or chemicals. And efforts are already underway in Canada.

BC Ferries is working to lessen the effects of underwater noise, especially along ferry routes that pass through critical habitats. WCS (Wildlife Conservation Society) Canada is encouraging the federal government to increase protective measures in the Arctic. They’re also working with international colleagues to address the increase of noise in the region as a result of new shipping routes.

While these initiatives demonstrate progress, tightening rules and regulations around noise pollution is an important measure for conserving wildlife in Canada.

4 . On Christmas Eve, a team of reindeer (驯鹿) will help Santa Claus deliver gifts to children all around the world. The reindeer, led by their fearless leader Rudolph, won’t be the only ones doing something special. Back in the highest Arctic, their cousins have a remarkable ability changing their eye color.

During the summer months, when the days are long and the sun is bright, reindeer’s tapetum lucidum (荧光膜), a mirror-like layer at the back of their eye, appears golden, which helps bounce the majority of light off the eyes, effectively acting like a pair of natural sunglasses. As winter comes, and the days become shorter and darker, the tapetum lucidum turns blue to absorb more light, allowing reindeer to improve their night vision and see clear in low light conditions.

With these adaptations, reindeer can adapt and thrive in one of the harshest environments on Earth. Unlike humans, reindeer can see well into the shorter Ultra Violet (UV) range. This UV vision enables them to spot food and predators more effectively in the snowy landscape. Lichens, a key part of their winter diet, absorb UV, so they show up dark against UV-reflecting white snow. Wolf and polar bear fur also absorb UV, so instead of disappearing against snow they pop out in high contrast, allowing reindeer to spot potential threats from a distance.

Reindeer change their eyes by adjusting their tapetum lucidum, which is made of collagen fibers. In winter, the collagen fibers become packed tighter, causing the tapetum lucidum to mainly reflect blue light. This change happens when reindeer dilate their pupils (瞳孔). In summer, the reindeer’s pupils return to a smaller size, which helps reindeer reduce the amount of light entering the eye.

But their unique adaptation may hurt them. Today, the increasing use of artificial lighting, especially during the winter months, poses a potential threat to their sensitive eyes. It can make reindeer lose their way, affecting their ability to survive in their challenging environment. So it is crucial for us to be mindful of our use of electricity and make efforts to minimize light pollution to ensure the well-being and survival of these magnificent creatures.

Microplastics in Water — a Wake-up Call for All of Us

Today researchers announced that they have found tiny pieces of plastic in water samples from around the world. These pieces are called microplastics and are so small that they are invisible to the naked eye and are very difficult to remove from the water. When in the water, they are swallowed by fish and other animals and then enter the food chain.

Even more concerning is the fact that the plastic has also been found in drinking water across the world. This means that we are drinking plastic every day. Scientists do not know what level of harm this will cause us in the future.

Microplastics come from a number of different sources, in particular from washing and drying synthetic (non-natural) clothing and from cosmetics and cleaning products, such as toothpaste and face washes. Microplastics are even found in the air outside and at our homes.

Almost every country across the world agrees that we cannot continue using so much plastic in our lives. We need to find a solution to remove microplastics from our oceans. We also need to introduce new taxes and other means to encourage companies to choose environment-friendly ingredients and recyclable packaging for their products.

We need to take personal responsibility, too. We all have the freedom to choose how we spend our money and what kids of business and products we support. Let’s work together to protect our environment, both now and for the future.

Remember: Reduce — Reuse — Recycle. (244 words)

8 . New research links outdoor air pollution — even at levels considered safe — to an increased risk of diabetes (糖尿病) globally, according to a study from the VA St. Louis Health Care System. The findings raise the possibility that reducing pollution may lead to a drop in diabetes cases in heavily polluted countries such as India and less polluted ones such as the United States.

Diabetes is one of the fastest growing diseases, affecting more than 500 million people worldwide. The main drivers of diabetes include eating an unhealthy diet, having a sedentary lifestyle and obesity, but the new research indicates the extent to which outdoor air pollution plays a role.

“Our research shows a significant link between air pollution and diabetes globally,” said Ziyad Al-Aly, MD, the study’s senior author and an assistant professor of medicine at the University of Washington. “We found an increased risk, even at low levels of air pollution currently considered safe by the US Environmental Protection Agency (EPA) and the World Health Organization (WHO). This is important because many industry lobbying (游说) groups argue that current levels are too stringent and should be relaxed. Evidence shows that current levels are still not sufficiently safe and need to be tightened.”

While growing evidence has suggested a link between air pollution and diabetes, researchers have not attempted to quantify that burden until now. “Over the past two decades, there have been bits of research about diabetes and pollution,” said Al-Aly. “We wanted to thread together the pieces for a broader, more solid understanding.”

The researchers also found that the overall risk of pollution-related diabetes tilted (倾斜) more toward lower-income countries such as India that lack the resources for environmental mitigation systems and clean-air policies. For instance, poverty-stricken countries facing a higher diabetes-pollution risk include Afghanistan, Papua New Guinea and Guyana, while richer countries such as France, Finland and Iceland experience a lower risk. The US experiences a medium risk of pollution-related diabetes.

1. What does the underlined word “stringent” in paragraph 3 mean?

A．Strict.	B．Slight.
C．Bright.	D．Ordinary.

2. What’s the purpose of Al-Aly’s team?

A．To identify the causes of diabetes.

B．To make better air pollution control policies.

C．To lead the study of diabetes and air pollution.

D．To figure out the link between pollution and diabetes.

3. Which country faces the lowest diabetes-pollution risk?

A．India.	B．Finland.
C．The US.	D．Guyana.

4. What can be the best title for the text?

A．Current pollution control levels need to be tightened

B．Diabetes is one of the fastest growing diseases globally

C．Air pollution contributes significantly to diabetes globally

D．Poverty-stricken countries face a higher diabetes-pollution risk

10 . Masses of ocean plastic are providing artificial habitat (栖息地) for otherwise coastal species, according to a new study published in Nature Communications. The study’s authors observed floating water bottles, old toothbrushes and waste fishing nets. The possibility exists that species may be evolving to better adapt to life on plastic.

A decade ago, marine researchers believed coastal species could not survive a trip across the inhospitable open ocean. Yet Japan’s 2011 tsunami (海啸), which sent some 300 species of Asian marine life riding floating plastic garbage onto North American shores, disproved that assumption.

Ocean plastic is “creating opportunities for coastal species’ biogeography to greatly expand beyond what we previously thought was possible”, Linsey Haram, a researcher and co-author of the study, said in a report.

The concept of species-covered plastic may sound like the story of ocean species’ victory in spite of human pollution. But that’s not quite the case, explains Juan José Alava, PhD, an expert at the University of British Columbia. In addition to transporting non-native species to new habitats where they may become invasive and destructive, the plastic is “basically an ecological trap”, says Alava. “That’s because small species on the floating structure may attract bigger animals to come for food. When these creatures enter garbage areas for food, they run a high risk of eating and/or becoming caught in plastic and dying.”

While scientists have found some types of bacteria (细菌) are able to break down plastic, thereby cleaning up garbage, it’s unlikely that the marine animals will have any such effect. “The 2021 UN report was clear that the increasing plastic pollution is putting the health of all the world’s oceans and seas at risk,” says Alava.

1. What does the underlined word “inhospitable” in Paragraph 2 mean?

A．Easy-to-spot.	B．Up-to-standard.
C．Down-to-earth.	D．Hard-to-stay.

2. What effect would ocean plastic have on coastal species according to Linsey?

A．Putting them at greater risk.

B．Causing them to grow bigger.

C．Enabling them to live in new habitats.

D．Freeing them from getting endangered.

3. What does Alava think of ocean plastic in Paragraph 4?

A．It increases some creatures’ curiosity.

B．It causes damage to all marine species.

C．It creates habitats for larger creatures.

D．It leads to the death of some creatures.

4. What would the author most probably agree with?

A．Ocean plastic must be dealt with.

B．It’s OK to throw plastic into the ocean.

C．Marine life may adapt to ocean plastic.

D．Ocean plastic may be cleaned up soon.
